I'm curious if anyone has used or considered Ecoflow for battery power?
Looks easy to set up, and has solar charging options.

I did get the River 2 Pro for use as an UPS for household wifi/Internet and phone. I figure it could provide power for lights, toilet, furnace, and water pressure when boondocking. I think the fridge might drain it too fast to be practical. A larger unit that might be more suitable would be very expensive.
